No Apparent Reason Boner. When you're just sitting there taking a test or listening to a sermon in church and for some random reason, you get a raging hard-on. Hopefully you are wearing tight jeans or tighty-whities and not gym shorts.

I finished with my test early but had to wait to leave because I didn't want to jab anyone in the back of the head with my Narb as I was leaving my seat.
